SMOKE AND cinnnn CONDENSER.

Specification of Letters Patent.

llat-ented Dec. 28, 1915.

Application filed March 13, 1914. Serial No. 82%,470.

To all whom it may concern I Be it known that I, EDWARD S. JONES, a citizen of the United States, residing at Mobile, in the county of Mobile and State of Alabama, have invented new and useful Improvements in Smoke and Cinder Gondensers, of which the following is a specification.

The invention has for an object a simplified and eflicient 111631151 01 the disposal of smoke and cinders from locomotives in such manner that they will be deposited upon the track or other suitable place in a form calcuplated to do the least harm.

- It is a particular aim to improve the smoke stack connections of a locomotive,

whereby, a fan may be used to carry off the discharge, occupying a minimum of space so that the limit of clearance on the right of way will not be exceeded.

It is also an object to enable the rapid assemblage of the device.

Another object is to provide a desirable exhaust fan construction and mounting for such use.-

The invention is applicable to the treatment of products from smoke-stacks of factories and other plants.

Additional objects, advantages and features of invention will appear, some of which will be. apparent from the following description, and from the drawings, in which, 7

Figure 1 is a side view of an engine equipped with my invention. Fig. 2 is a cross section thereof taken on the line 22 of Fig. 1. Fig. 3 is adetail of fan construction and mounting.

There is illustrated an engine 10, which may be of any usual construction; including a boiler 11., a steam dome 12 and smoke stack 13. The smoke stack is curved toward the rear closely over the boiler, and is provided with a fiared terminal member 1 1, seated at its larger and rearmos't end against the forward end of a substantially cylindrical fan casing 15, having a footing 16 secured upon the boiler, as shown. The casing has secured thereto at' each end a spider 17 in which a fan 18 is revolubly mounted, includ ing a driving sprocket 19 incl osed in a chain housing 20, projecting radially to an opening 21 in the member 14. Engaged on the sprocket there is an endless chain 22 from a turbine 23 mounted on the boiler beside the casing 15. It will of course be understood that any other suitable connection between the ,turbine and the fan may be utilized. The turbine may be of any suitable type, and is operated by steam supplied through a pipe 21 from the dome 12. Immediately adjacent the dome a valve 25 is connected in this pipe, having the oppositely extending operating arms 26 from which respective operating cables 27 are extended to the engine cab. It will of course be understood that drawing upon one of these cables will start the turbine while operation of the other will cut off the steam supply.

Extended from the rear end of the casing 15 there is a reducing connection 28, similar to the member 1 1 in the manner of its attachment, buthaving a branched terminal portion connected to respective flues 29, extending downwardly on respective sides of the engine, being carried under the boiler at a suitable point, and turned outwardly, as at 30, so that cinders may be discharged directly upon the heads of the rails. The members 14: and 28 are provided with bosses 31, in planes with respective arms of the spider 17, bolts 32 being engaged through the bosses and with the arms to hold the members 1% and 2S securely upon the casing 15. The spiders 17 may be held by means of the same bolts engaging in lugs within the casing.

The turbine 23 is provided with a branched exhaust duct 3-1, respective branches of which enter the fines 29 near the point where they are connected to the member 28. By this construction. when the tan is operated, the exhaust from the fan is directed into the products passing through the fines under action of the fan, serving to dampen them and increasing the specific gravity of the smoke and cinders, so that they will fall rapidly.

In order to facilitate the starting of a fire in the fire-box of the engine a port 35 and closure 36 is formed in the smoke stack 13 carried pivotally upon the arms 37 one of which is cranked pivoted concentrically with the curve of the stack, the closure being held in closed position by gravity, and being opened by means of a cable 39 con nected to the crank arm 37. In starting a fire, the port 35 is opened so that smoke may escape directly from the stack to the open 'air as long as necessary. If desired, compressed air may be used for clearing the ack and flues upon starting a fire, by leading a pipe 42 into the stack from a suitable source.

It will be apparentfrom the foregoing that an extremely simple and practical construction is provided liable in a minimum degree to derangement and being of high efficiency. The enlargement of the diameter of the fan-casing as compared to that of the stack and flues reduces the liability of back. pressure on account of the fan elements, to .a great extent.

There is illustrated at 42 a pipe leading into the smoke-stack, which may terminate at a suitable nozzle, not shown, for inducing a draft through the stack and fines 29. The pipe leads from the engine cab, and is connected to a suitable source of compressed alr, admission of which to the pipe may be controlled within the cab in way.

That is claimed:

A smoke stack of a steam engine bent back upon the engine, a fan placed in the stack, ducts leading from the fan for conveying the smoke and cinders away, a steam turbine for driving said fan, an exhaust pipe from said turbine for conducting the exhaust steam to said ducts, an auxiliary air opening in the forward part of said stack, a cover for said opening and means for opening and closing said opening.

any desired In testlmony whereof I have hereunto set my hand in presence of two subscribing witnesses.

EDWARD S. JONES.
